A ship’s navigation instrument produces and pro-

vides a variety of information necessary for safe

navigation.

A number of researches’ efforts to provide more

advanced information for safe navigation.

Related studies include a study on collision

avoidance assistant system using fuzzy case-based

reasoning[1] and a study on a conceptual model for

collision avoidance for ontology-based fuzzy CBR

support system[2], and a study on a system that au-

tomatically sets up routes and supports the descrip-

tion of the set route for mates on small ships, who

are lacking of expertise[3]

In addition, there are a study that built an embed-

ded system that can control ships steering system of

ships with speech wheel order[4], speech-

recognition-based intelligent ships steering control

system suggested by Gyei-Kark Park and Ki-Yeol

Seo[5], and a study on ontology based fuzzy ships

steering control system[6].

However, studies so far have been carried on sys-

tems for navigators without expertise on small ships

without automatic control, and related systems or

studies which can provide comprehensive infor-

mation efficiently for experts are lacking.

This study tries to suggest data fusion models

necessary for the construction of the system to un-

derstand, unite, and provide the multimedia marine

information for mates. A ship’s navigation instru-

ment produces and provides a variety of information

necessary for safe navigation.

2 OVERVIEW OF A DATA FUSION MODEL

FOR NAVIGATION INFORMATION

Such a process as Figure 1 is necessary for establish-

ing a data fusion model to recognize a situation us-

ing the multimedia navigation safety information

provided by diverse navigation equipment, induce

the information needed for decision-making, and

provide it linguistically.

First of all, this paper composes a data field by

navigation equipment by analyzing the raw data

produced and provided by navigation equipment

such as GPS, ARPA, AIS, NAVTEX, VHF, etc. and

then establishes a knowledge representation model

to express the data in each data field and the rela-

tionship between objects as subjects between attrib-

utes linguistically using a semantic network.

Next, this paper establishes a data fusion model

using a knowledge representation model, and pro-

vides the information obtained newly by providing

the information of a data fusion model in a language

ABSTRACT: Ship mates should be aware of images, numerical values, texts and audio-based information of

radar, AIS, NAVTEX, VHF, and etc. for safe navigation. However, it is very complicated and difficult for

them to acquire such information and use it as data for decision-making for safe navigation while keeping

watch for navigation. So, a system to understand, unite and provide multimedia marine information for mates

in voice is necessary. This study tries to suggest data fusion model of the navigation and communication sys-

tem.
